Is Melting Candle Wax A Chemical Or Physical Change
Is Melting Candle Wax A Chemical Or Physical Change. The wax is heated to a temperature that causes it to melt and solidify into a solid mass of wax. Hope it helps you ☺.

Kaypeeoh72z and 2 more users found this answer helpful. Also, the produced gaseous substances cannot reverse back to form the solid wax again, which depicts the process as a chemical change. Melting of wax is a temporary and reversible change on cooling, wax solidifies, and no new product is formed while burning of a candle is a permanent change i.e.
The Melting Of The Solid Wax To Form Liquid Wax And The Evaporation Of Liquid Wax To Form Wax Vapour Are Physical Changes.
The process of burning is a chemical reaction that produces heat, light, and other physical effects. Yes, burning a candle is a chemical change because due to the burning of a candle carbon dioxide water vapors, heat, and light are released. Which of the following are physical changes and which are chemical changes ?

This is what causes the light and heat to be produced. When the physical state of a substance changes, no new products are formed. What kind of change is melting of wax?
Candles Are Made Up Of Wax Which Melts During High Temperature.
The flame, is a chemical reaction, which burns wax vapor, which combines with oxygen to produce carbon dioxide and water vapor. New substances are being formed and old ones consumed, so this is a chemical change.the melting of the candle wax is a physical change. Melting of wax is temporary and wax can settle again on cooling and turns into a solid.
Of Course, Its A Physical Change.
Hence, the statement saying, melting of wax is a physical change but burning of wax is a chemical change, has been explained above. Though the burning of candles is not a physical change but melting of wax is a physical change. Share it on facebook twitter email.
Melting Of Wax, By Itself, Involves A Change Of State From Solid To Liquid.
Wax of candle is in solid state and melts to liquid state at high temperature. Correct option is c) no new substances are formed. In the case of a wax candle, however, the process is not chemical, but physical.
